This paper proposes a radial rotating system and sandwich structure triboelectric nanogenerator (RS-TENG) to integrate triboelectric nanogenerators (TENGs) on the blades of a rotating turbine for the first time. The TENG is a future-oriented technology for harvesting mechanical energy from the environment and transforming the energy into electrical power. However, it is still necessary to study practical structures that can be applied to actual environments outside of the laboratory. The proposed RS-TENG structure can generate and combine multi-phase alternating powers to generate an enhanced constant output power. The radial rotating system simultaneously operates six TENGs of which each TENG generates a signal with a phase difference of 60 degrees, at one rotation. These signals are combined after the rectifiers and a slip ring to provide the advantage of multiple phases. In the sandwich structure, two TENGs are symmetrically positioned on the sliding plate and operate at the same time. This facilitates the efficient use of the limited area and approximately doubles the output voltage of the RS-TENG. On the basis of several analyses, it was revealed that the RS-TENG has a power density value of 30.27 mW/m², lighting up 245 LEDs without fluctuations. Ultimately, the RS-TENG represents a structure that can be integrated into turbines and is thus capable of expanding the applicability of TENGs.

本文提出了一种径向旋转系统和夹层结构摩擦纳米发电机 (RS-TENG)，首次将摩擦纳米发电机 (TENG) 集成到旋转涡轮机的叶片上。TENG 是一项面向未来的技术，用于从环境中收集机械能并将能量转化为电能。然而，仍然有必要研究可应用于实验室外实际环境的实用结构。所提出的 RS-TENG 结构可以产生和组合多相交流电以产生增强的恒定输出功率。径向旋转系统同时操作六个 TENG，其中每个 TENG 在旋转一圈时产生相位差为 60 度的信号。这些信号在整流器和滑环之后组合，以提供多相的优势。在三明治结构中，两个 TENG 对称地放置在滑板上并同时运行。这有利于有限区域的有效利用，并使 RS-TENG 的输出电压大约翻倍。根据多项分析，RS-TENG 的功率密度值为 30.27 mW/m²、点亮245个LED无波动。最终，RS-TENG 代表了一种可以集成到涡轮机中的结构，因此能够扩展 TENG 的适用性。
